rMSI2::ProcessImages() - checksum warning #1

Closed goterm closed 1 year ago

goterm commented 2 years ago

Hi,

when I run: rMSI2::ProcessImages(proc_params, data_desc)

the processing starts and ends without errors but I get a warning:

Parsingng ROI info of imzML 1 of 1 Loading image 1 of 1 Parsing XML data in imzML file... Checking ibd UUID...OK WARNING: Checksum validation is disabled, data may be corrupt! Calculating the new mass axis... .... is this something to worry about? Can I enable/control the validation?

thanks!

Hi,

nothing to worry about. The checksum verification is disabled by default because it may take a very long time for large datasets. Moreover, some imzML files obtained from some vendors do not have a properly calculated checksum and will throw a false error after a long wait.

The checksum validation is implemented in rMSI2. You can force it to be calculated using the verifyImzMLChecksums = T argument to the ProcessImages() function.
